To all whom 75 may concern Beit known -that I, GUSTAF A. HERMAN- soN, a citizen of the United States, Iresiding in-'Chicago,in thecounty of Cook and State of Illinois, have invented a new and useful Improvement in Gar-Couplers, of whichthe f part of lthis specification, Figure l is a the lock in Vposition for uneoupling and for throwing zthe Iknuckle open, and in which the draw-head may have a closed housing over the 4upper end -o'f the dock, and the lock -belifted from its lower end 4by a bot` tom lift lever -mounted on the front end lof the ycar -and extending to the side thereof.

`My inventionconsists in Kthe means Iemploy -to practically accomplish this object or result. lThat is `to say, itconsistsvin a car coupler comprising lin combination, a draw-head having in its bottom web or floor a lock-setledgeandaguide'or cam to -guide the lock into engagement with said lock-set ledge when it is lifted, `a knuckle having a rear -armor tail furnished with a knuckle throwing incline on its lower face, a lock having a lock-set shoulder near its lower end adapted to engage said loclcset ledge on the draw-head, and a further shoulder adapted to ride on the tail of the knuckle, and a bottom Ilift lever pivotally mounted on the front end of the car yand extending to vthe side thereof, :preferably just adjacent to the front sill of the car, and provided with a lift-ing arm adapted to engage the lower end of the lock, and also furnished with a knuckle throwing incline or arm adapted to engage t-he tail of the knuckle to throw the knuckle open; said bottom lift lever swinging vertically on its pivot to raise the lock and also swinging horizontally to accommodate or allow for the longitudinal movement of the drawhead and draw-bar in respect to the car frame; the lifting arm of said bottom lift lever engaging the guide cam on the drawhead to swing or guide the lock-set shoulder of the lock onto the lock-set ledge of the draw-head.

-My invention further consists in thenovel construction -o'f parts and devices and in the novel'eombinations of parts `and devices herein shown and described and more particularly `specified in the claim.

In the accompanying drawing forming a central, vertical, longitudinal section Vof the c'ar coupler Y embodying my invention. Fig. 2 'is a similar .view'of the lock on its lock-set position. Fig. 3 is a horizontal section on line 3-3 of Fig. l. Fig. d vis a vertical section 'on -line 4-4 of Fig. l. Fig. 5 is a 'front end thereof and pivotally connected thereto by ythe bracket H.

The draw-head B has the customary guard arm Z) and pivot-arm '221 through the upper and lower lugs of which the pivot pin C extends to pivotally connect the knuckle vD Vwiththe draw-head. The drawhead B has a closedsocket or cavity b2 to receive the lock, in which the lock is adapted to move up and down, the upper end of -this lock socket being closed by vthe integral housing portion if of the drawhead. The draw-head is further provided in its bottom web or :floor b4 with `a transverselyextending slot-for -passage b5 for the bottom .lift lever to Swing in, and with depending vertical lguard webs or flanges Zi v'bito vprotect and house the inner end of Athe vertically swinging bottom lift lever.

The draw-head is further provided with a lock-set ledge or shoulder bs adapted to engage the lock-set shoulder f of the lock,

and thus support the lock in position for uncoupling. The draw-head B is further provided with a guide cam or incline adapted by engagement with the lifting arm g of the bottom lift lever to guide or swing the lower end of the lock forward as it is lifted, so that its lock-set shoulder f will properly engage the lock-set ledge 58 of the draw-head.

The knuckle D has the customary front arm or nose Z and rear arm or tail (Z1, which is furnished on its under side with a knuckle throwing cam or incline d2, and also with a stop shoulder d3 adapted to engage a corresponding stop shoulder Z910 on the drawhead to limit the outward or opening movement of the knuckle.

The lock F is preferably square or rectangular in cross section, and is adapted to move up and down in the lock socket of the draw-head, and isprovide'd with a lock-set shoulder f near its lower end adapted to engage the lock-set ledge bs of the drawhead and support the lock in position for uncoupl'ing. The lock F is further provided with a shoulder f1 adapted to engage and ride upon the rear arm or tail of the knuckle and thus support the lock in position for coupling as the knuckle swings into its closed position. The lock F is further provided at its lower end with a guide eXtension f2 having an inclined rear face f3 to guide the upper end of the lifting arm of the bottom lift lever against kthe shoulder lor projection f4 at the lower end of the lock. The lock F is further provided with a cam or incline f5 on its rear face near its lower end which, by engagement with a cam or incline o on the draw-head tends to throw the lower end of the lock forward as it is lifted, and thus cause its upper shoulder f1 to properly engage the tail of the knuckle and support the lock in position for coupling.

The bottom lift lever G extends laterally or transverselyto the side of the car at the front end thereof, and is pivotally connected thereto by a support or lifting-lever bracket H, preferably attached to the front sill of the car, and having a pivot pin 7L extending through lugs h1 between which the lifting lever loosely fits so that it may not only swing vertically on its pivot pin t as required for lifting the lock, but also swing horizontally between said lugs h1 to the eX- tent necessary to accommodate the longitudinal or backward and forward movement of the draw-bar in respect to the car frame. The bottom lift lever G is furnished with a lifting arm'g adapted to engage the shoulder fi near the lower end of the lock to lift the lock and also to engage the cam or incline b9 on the draw-head to swing the lower end of the lock slightly forward and thus cause its lock-set shoulder f to properly engage the lock-set ledge bs of the draw-head. The bottom lift lever G is further provided with a knuckle throwing cam, incline or curved arm g1 which engages the knuckle throwing cam orincline d2 on the under face of the rear arm Z1 of the knuckle D and thus operates to throw the knuckle open.

The lifting arm of the bottom lift lever first engages the lower end of the lock and raises the same suiiiciently to permit the knuckle to open, and then the further upward movement of the 'inner end of the bottom lift lever Gr causes its knuckle throwing` arm g1 to engage the knuckle throwing ineline on the tail of the knuckle and thus automatically throw the knuckle open.

I claim n acar coupler, the combination with a draw-head, knuckle and lock, of a pivotally mounted bottom lift lever for the lock adapted to vibrate horizontally to allow for longitudinal movement of the coupler, said draw-head having a lock setting guide cam b9 for the lifting arm of the lever, said knuckle having a rear arm ortail furnished with a knuckle throwing incline, said lock having a depending guide extension f3, and

said bottom lift lever having a lifting arm g adapted to engage the lower end of the lock to lift the same, and a knuckle throwing incline engaging the knuckle throwing incline on the tail of the knuckle to throw the knuckle open upon a continued upward movement of the lift lever.
